Getting the element factory name.

[Sameer Naik]

Hello,

I am using the gstreamer-0.10.34. I would like to know how do i get
the name of an element factory.
I create an element, say

GstElement *element;
GstElementFactory *factory;

element = gst_element_factory_make ("queue2", NULL);
factory = gst_element_get_factory (element);

I need to query the factory such that it return "queue2" as its name.

In an earlier release of gstreamer i used to call:
factoryname = GST_ELEMENT_NAME (factory);

And i would get the factoryname as "queue2". But in the 0.10.34
release it returns "elementfactoryXXX", where XXX is a random number.
I am writing a function to return a reference to am element belonging
to a particular factory.

Thanks and Regards
~Sameer

I just checked up on how gst_bin_get_by_name () call works.

children = gst_bin_iterate_recurse (bin);
result = gst_iterator_find_custom (children, (GCompareFunc)
compare_name, (gpointer) name);
gst_iterator_free (children);

And in the compare_name function
eq = strcmp (GST_ELEMENT_NAME (element), name);

It seems GST_ELEMENT_NAME () is how it is supposed to be done. Looks
like something is wrong in my code.

Thanks

GST_ELEMENT_NAME on an element will give you the element name. If
that's what you want - great.

However, you ASKED for the element factory name. For that, you can use
GST_PLUGIN_FEATURE_NAME(elementfactory).

Note that you want to call this on the element factory, NOT the element.
